Infrastructure Monitoring – Overhead Line Equipment on In-Service Vehicles (Dynamic OLE Data)
Authority: NETWORK RAIL INFRASTRUCTURE LIMITED (Central government)
What is being bought2 lots · detail below
Published requirement descriptionService Scope
Network Rail (NR) is issuing a Tender Notice for acquiring services related to Monitoring of the Overhead Line Equipment (OLE) in Great Britain.
